Numerical patterns in the coordinate grid (5th grade math)

This is an introduction to graphing points in the coordinate grid that follow a simple numerical pattern. The patterns we look at all form a linear geometric pattern in the grid (the points look like on a line). The patterns in this lesson are either given algebraically (such as y = 12 - 2x), or we first continue the existing pattern in the given ordered pairs, and then write the rule in algebraic form (such as y = 2x or x + y = 10). The lesson ties in with the common core standard 5.OA.3 and covers most of it, though not completely. The follow-up lesson found here covers the rest of the story: https://www.youtube.com/watch?v=w5g_x1Z4Zng (This common core standard requires that the patterns be given using two given rules, one for the x-values and the other for y-values, whereas in this particular lesson, the patterns are deduced from the given ordered pairs or from the way the x and y values relate to each other.)
